CALKED SADDLE Chester V. Smith, Lancaster, Pa. Application October 3,1950, Serial No. 188,182

1 Claim. l

This invention relates to a pipe coupling and more particularly to thattype of pipe coupling known as a calked saddle, commonly used to bring anew line into an old established line.

The object of the present invention is to improve on the construction ofthe saddle so that it may be more easily and more thoroughly sealed.

A further object of the present invention is to provide an integralcollar formed in one half of the calked saddle to serve as the feed lineinto the old established line.

It is a further object of the present invention to provide tits tosupport the upper half of the saddle at the juncture between the upperhalf and the lower half so that the upper half of the saddle is heldslightly above the lower half to permit lead to freely ow andpermanently seal the two halves of the saddle.

It is a further object of the present invention to provide a beveledgroove at the juncture of the two saddles to serve as a means forintroducing the lead in the sealing operation.

With the foregoing and other objects in view, the invention resides inthe novel arrangement and combination of parts and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of the invention herein described maybe made within the scope of what is claimed without departing from thespirit of the invention.

The invention is shown in the accompanying drawing in which:

Figure 1 is a side elevation.

Figure 2 is a vertical cross section showing the established line pipein position.

Figure 3 is a longitudinal cross section showing the established linepipe brokenly.

Figure 4 is a detail view of the juncture between the two halves of thesaddle.

Figure 5 is a side elevation showing the saddle with a right anglejuncture.

Figure 6 is a similar view showing the saddle with the juncture at 45.

The pipe coupling known as a calked saddle is used in connecting a newline to an old established line and is formed in two parts, the lowersemicylindrical section 8 and the upper semicylin- Vdrical section 9.Integral with the upper section 9 is a hub l0 formed with a restricteddepending outlet I I.

The lower half 8 of the saddle is formed with longitudinal channels I2receiving the longitudinal lips I3 of the upper half of the saddle.Adjacent the lips I3 are tits I4 arranged in spaced relation, as shownin Figure 3, and serving to 2 support the upper half of the saddleslightly spaced from the lower half of the saddle to provide acomparatively equal space between the upper and lower halves of thesaddle for the reception of a sealing medium such as molten lead.

The lower half of the saddle is provided centrally with a series ofupstanding teeth I 5 which may be filed or chipped in the seating of thesaddle around the old line pipe I6. The interior line of juncturebetween the upper and lower half is beveled at II to provide a groove I8serving as a conduit for the molten lead and to insure the lead flowingthroughout the entire length of the longitudinal juncture.

In use the old line pipe I6 is bored at I9 to provide a hole for thereception of the integral inlet Il of the hub I0. The upper half of thesaddle is placed in position and the lower half slid onto the lips I3,filing or breaking the teeth I5 to provide a snug fit between the saddleand the old line pipe I6. A screw 28 is tightened to temporarily holdthe two halves of the saddle in position. Calking 2i is tamped betweenthe saddle and the old line pipe and molten lead is poured into thegroove I8 completely filling the groove I2 and forming a seal betweenthe upper half of the saddle and the lower half of the saddle which alsoeffectively seals the saddle to the old line pipe. The flow of themolten lead so as to completely iill the groove I2 is insured by thetits I4 sup-porting the upper half of the pipe slightly above the lowerhalf of the pipe to provide a channel for the now of the sealing medium.

The upper edge 22 of the channel I2 is bent inward toward the body ofthe pipe, terminating a slight distance from the pipe providing a slit23 into which the molten lead may be poured when the saddle is used in ahorizontal position.

Figure 5 shows the saddle formed with the hub at a angle to the saddlewhile Figure 6 shows a modification showing the hub at an angle of 45.Applicants improvements in the construction are the same in both ofthese modications and are directed primarily to the use of the integralinlet ange and the construction of the saddle to provide thoroughsealing.

What is claimed is:
